================
Comment at: test/LTO/X86/type-mapping-bug.ll:23
+; getting a mapping from %DstType, which has previously used as
+; a destination type.
+%Tricky = type opaque
----------------
This explains what happens without the above change to IRMover.cpp, but it doesn't explain what happens after you make that change and why that behavior is correct. Could you add that information here? Other than that, looks good - thanks for fixing this!
